Technology Update
40 July/August 2007
Gräbener, Germany, have undertaken a
complete retrofit of a forming press within
just three weeks. The company carried out
this task at Erndtebrücker Eisenwerk GmbH
& Co KG (EEW), a company that has been
using a pipe forming press for just over 10
years.
A similar Gräbener pipe forming press
installed at EEW’s Korean subsidiary has
proven to be considerably quicker with
more precise bending results. Due to the
booming nature of the pipe market, a swift
retrofit was essential to the operational
stability of the plant.
The retrofit involved installation of the
deflection compensation and reworking of
the lower tool, installation of the plate and
pipe handling system, complete retrofit to
the hydraulics concept and a completely
new electric system and control. Each pipe
duct, connection to the cylinders, and the
entire piping was engineered and drawn by
means of Catia V5 (3D CAD program) and
pre-installed at the Gräbener works.
The construction, installation and start-up of
the new system had to be planned. Prior to
this, segments of the old press also had to
be dismantled. Gräbener‘s time limit for the
dismantling and cleaning of the remaining
machine parts and foundation was one
week, with two weeks for installation and
start-up. The usual period for the installation
and start-up of pipe forming presses is four
to five weeks.
The entire retrofit was carried out between
December 2006 and January 2007. The
first pipe left the ‘new’ machine on January
05, 2007.

Reduced consumption costs
with economical marking systems
Leibinger, Germany,
manufactures the
JET2SE range of ink-
jet printers, which are
used in a range of
industries, including
automotive and
pharmaceutical, for the
labelling of packaging,
and the marking of
metal, plastics, glass
and coated surfaces.
The company has
developed ECOsolv,
a new solvent
recovery system
capable of reducing
the consumption
of solvents in printing by up to 50 per cent. ECOsolv is designed to complement the
features of the Leibinger JET2SE range.
Leibinger ink-jet printers use the continuous ink-jet principle for fast, non-contact
printing.
The JET2SE series also features a unique nozzle seal, which ensures an ‘instant start’
at the push of a button, even after long standstill periods.
